LM4040D25QDBZR

Texas Instruments · Voltage Reference · SOT-23-3

LM4040D25QDBZR from Texas Instruments, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CATHODE bidirectional Parallel current/voltage input; the cathode must be supplied with at least the minimum regulation current IZ,min (45 µA typical) and the cathode current should be kept at or below the 15 mA recommended maximum (25 mA absolute maximum continuous).
2 ANODE passive General-purpose pin, normally grounded, and serves as the common reference terminal of the shunt reference.
3 * passive Must be left floating or connected to the anode (pin 2) because a parasitic Schottky diode exists between pins 2 and 3; TI recommends connecting it to the anode in applications with high EMI or significant high-frequency switching noise.
